4 Claims. (01. 70-2) This invention relates to fastening devices, especially to locks, and more particularly to a hasp-lock of the type adapted to secure swinging doors in closed position relatively to the door-frame.

An object of the invention is to provide improved hasp-lock fastening devices for use as standard equipment upon a series of cabinets installed along the right-of-way of a railroad and intended for containing operating relays, tools and supplies, etc.

It is desirable that such cabinets be secured against access to their interior by unauthorized persons, but readily accessible to numerous individual operatives each provided with a master key adapted to lock and unlock all the padlocks by which term the fastening devices for such cabinets are known generally to such operators, whether or not they include a conventional padlock or any suitable locking device not operable by hand without some form of key or actuating member.

Other objectsand advantages will appear as the description of the particular physical embodiment selected to illustrate the invention progresses, and the novel features will be particularly pointed out in the appended claims.

In describing the invention in detail and the particular physical embodiment selected to illustrate the invention, reference will be had to the accompanying drawing and the several views thereon, in which like characters of reference designate like parts throughout the several views,

and in which:

Figure 1 is a view in horizontal section of a hasp-lock fastening device, the construction of which the invention has been embodied, and

shown in position upon the associated parts of a cabinet to which it is applied including portions of the door-frame and swinging door; Fig. 2 is a front elevational View of the device as shown by Fig. 1, with some parts broken away to more clearly show the construction; Fig. 3 is a view in side elevation of the device shown in Figs. 1 and 2; Fig. 4 is a detail view like Fig. 3, but showing the keeper member separately; Fig. 5 isa plan view of the mounting pivot member for the'hasp, taken separately; Fig. 6 is a fragmentary, detail view like Fig. 1, but showing a modification.

In the now preferred embodiment of the invention selected for illustration, and referring 'first to Figs. 1 to 5 inclusive, the reference character ll designates generally a swinging door, such as the door of a cabinet of the type known as a relay cabinet, being one of a series installed along the right-of-wayof. a railroad, thedoor frame being designatedgenerally as I2, while l3 designates'an inner panel, adapted to be engaged with -a rabbetted portion M of the upright free edge of the door, which it is desired tobring into firm, snug contact there with.

hasp lock fastening comprising-a hasp-element i5 mounted pivotally near the upright edge of the door, and carried bodily by the door, beingalso adapted to swing aboutitspivot into juxtaposition with a keeper element [6 when the door is closed. I

The hasp element includesa mounting plate or member I1 of a size and shape suitable to fit within a yoke l8formed at the pivot end of the hasp member, this mounting plate being secured to the door by a bolt-l9 transfixing the door and mounting plate, the latter having an opening 20 through which the bolt passes, and wings 2| so spaced as to accommodate the squared head 22 of the bolt, preventing it from being turned from the outside of the door. The inside end of the bolt.23 is provided with the usual nut and washer securement. p

The outer faces of the wings and adjoining.

In pursuance of the invention, I .provide a part of the mounting plate ll areshown as provided with open sockets 24' toreceive the pivot posts 25 with which the yoke I 8 is furnished, and spurs ZB may be provided to prevent turning movements of the mounting plate, so

that when the hasp member I5 is swung out of engagement with the keeper l6 it will be maintained in its horizontalplane.

The shank 21 of the hasp member may desirably be trough-shaped in cross-section forthesake of strength with lightness andat its free end the hasp has, a head ,28 in which is fitted a set-screw 29 which is provided with a part 36, designed to serve asm'eans to permit the screw to be operated readily byhand, for locking purposes.

In the form of construction shown in Figs. 1 to 4 inclusive, the manual operating means takes the form of a wing-nut',.fixed'bya pin 3| vto the shank of set-screw 29, and either wing, or both wings 32 of this nut may bedesirably pierced, as at 33, to receive the loop 34 of a conventional padlock 35.

When the padlock is in place, its loop 34 hangs between the flanges 36 each side of the trough shaped portion 21 of the hasp member, so that the wing nut cannot be turned until ridge 3'! around the seat 38 against which the nose of the set-screw 29 bears, and this ridge prevents any chance of a lateral escape by slipping of the set screw when the latter-has beenv firmly driven home.

The preferred shape and extent of this ridge 31 is best shown in Fig. 4, from which it will be clear that the part 31 constitutes a substantial barrier against the introduction of a tool, such as a screw-driver, in an effort to reach and displace the set screw 29.

Such tampering is further prevented by a high wall part 39 of semicircular contour, reinforced at its rear by a buttress 40. The keeper also is made with a stout L-shaped base having a lug 4| secured to the door-jamb l2 by screw 42 which is protected by the hasp member 21 from being withdrawn when the door is closed; and the base plate lug 43 maybe desirably secured firmly by a square headed wood screw 44, or other suitable securement, according to the character of the cabinet to which the device is applied.

It will be readily understood from the foregoing disclosure that the hasp-lock-fastening device is very strong, sturdy, economical to manufacture and to install; cannot be readily removed, and is proof against tampering unless the latter be studied and carried to a destructive extent, and even such malicious interference will be at least discouraged if not prevented to a large extent. 1

The same is true of the modification illustrated in Fig. 6,which is merely illustrative of a considerable range of diverse forms in which the invention may be embodied by those skilled in the art, upon the basis ofthe disclosure found herein.

Fig. 6 shows a set screw 45 which has a noncircular head 46 adapted to receive a removable operating key 41 in place of the wing nut 30 shown in Fig. 1, but otherwise operating in the same manner. g

It will be noted that the head of the hasp element is provided at 48 with a protective wall which extends to a distance sufficient to prevent easy operation of the set-screw when the key 4! is not in place. This form of device is available for many applications of the device where the risk of interference is less than warrants the provision of a conventional padlock, and in fact the form of lock shown in Fig. 6 may be, and is, regarded as a padlock in the terminology of railroad equipment.

Although I have particularly described one particular physical embodiment-of my invention and explained the operation, construction and principle thereof, nevertheless, I desire to have it understood that the form selected is merely illustrative, but does not exhaust the possible physical embodiments of the idea of means underlying my invention.

This application is a division of my prior application Serial No. 7,323, filed February 20, 1935, for Door fastener, now Patent No. 2,0;775526, granted April 20, 1937.
